God gave us free will. He also gave the angels free will, and some one third of all angels fell from heaven, including Lucifer/Satan.
Humans are sinful and have not been following God's commandments, and sinning over and over. We can't have eternal life because of our sin, that's why our bodies die now (because Adam and Eve sinned). God doesn't show himself because of all of this sin, but Jesus will come back to the Earth when the law He laid out is made void, when the antichrist requires people to take the mark, and if you don't take the mark you'll end up being persecuted. All Christians at the end will be persecuted and killed for their beliefs. But their bodies dying means nothing, because when Jesus comes everyone who believes in Him will be raised and live forever after.
So the question is why is this stuff happening from a Christian view? It's not that God is doing it or letting it happen as if He can't do anything to stop it. He will stop it, it will happen. For now humans are just sinning against each other, and hurting each other for their own benefit. God predicted that stuff to happen first. Revelation in the bible talks a lot about it.
One idea is that He will come when the laws that are kept in effect have made void God's laws.

The 10 Commandments List in Exodus 20:2-17
“I am the LORD your God, who brought you out of the land of Egypt, out of the house of bondage. You shall have no other gods before Me.
“You shall not make for yourself a carved image—any likeness of anything that is in heaven above, or that is in the earth beneath, or that is in the water under the earth; you shall not bow down to them nor serve them. For I, the LORD your God, am a jealous God, visiting the iniquity of the fathers upon the children to the third and fourth generations of those who hate Me, but showing mercy to thousands, to those who love Me and keep My commandments.
“You shall not take the name of the LORD your God in vain, for the LORD will not hold him guiltless who takes His name in vain.
“Remember the Sabbath day, to keep it holy. Six days you shall labor and do all your work, but the seventh day is the Sabbath of the LORD your God. In it you shall do no work: you, nor your son, nor your daughter, nor your male servant, nor your female servant, nor your cattle, nor your stranger who is within your gates. For in six days the LORD made the heavens and the earth, the sea, and all that is in them, and rested the seventh day. Therefore the LORD blessed the Sabbath day and hallowed it.
“Honor your father and your mother, that your days may be long upon the land which the LORD your God is giving you.
“You shall not murder.
“You shall not commit adultery.
“You shall not steal.
“You shall not bear false witness against your neighbor.
“You shall not covet your neighbor’s house; you shall not covet your neighbor’s wife, nor his male servant, nor his female servant, nor his ox, nor his donkey, nor anything that is your neighbor’s.”
10 Commandments ListAs you can see most of these are ignored today. But the main thing is going to be when the antichrist asks to be worshiped as god. Jesus came and said there were 2 commandments (I believe it's because they encompass the 10). His two were:
Matthew 22:37
Jesus said unto him, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind. 38 This is the first and great commandment. 39 And the second is like unto it, Thou shalt love thy neighbour as thyself. 40 On these two commandments hang all the law and the prophets.So one of the 2 is to love God with all of our hearts and souls and minds. He doesn't want people worshiping others, which is really not right to do since God made everything and anybody else asking to be worshiped doesn't deserve worship.
TLDR: I'm sorry this became a really long answer. The short answer is that free will is happening, but God foretold what would happen, and Jesus is coming at the right time, we just have to wait for the antichrist to act like he's god and require worship.
